RIVET=SETT|NG MACHINE.

SPECIFICATION forming part of Letters Patent No. 270,555, dated January 9, 1883.

Application filed August 25, 1882. (No model.) 7

To all whom it may concern:

Be it known that I, CLARK M. PLATT, of Waterbury, New Haven. county, State of (Jonnecticut, have invented a new and useful Improvementin Rivet-Setting Machines; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying sheet of drawings, making part of this specification.

This invention is in the nature of an im provement in rivet-setting machines; and the invention consists in a rivet-setting machine provided with an immovahlereceiver, having springjaws, a pivoted anvil-bearingarm, united to a forked vertical lever by a link, and an operatinglever provided with a tripping device, all constructed, arranged, and combined in the manner more particularly hereinafter described and claimed.

In theaccompanying sheet ofdrawings, Figure 1 is aside elevation of my rivet-setting machine, partly in section, showing an vildropped from the receiver; Fig. 2.a cross-section taken in the line a m, Fig. 1; Fig. 3,aside elevation, partly in section, showing the anvil up to the receiver; Fig. 4, a longitudinal section of anvil, sleeve, and spring; Fig.5,asection through 1 y, Fig. 3, showing the receiver and its jaws' in plan.

Similarletters ofreferenceindicate likeparts in the several figures.

This invention is in the nature of an improvement in the riveting or eyeleting machine patented to me on the 8th day of November, 1881. The details of the construction and operation of the feed-box, guide-channel, and their accessories being the same in every particular, they therefore need no further de scription now.

In the rivet-setting machine so patented by me, however, the receiver or the device that catches the rivetsas they emerge from the end of the channel-way was pivoted so that it could be carried down to the anvil, and, by means of a spring, recover its normal position.

-.In that machine, also, the anvil was rigidly In my present and improved machine, Arapresents the receiver, which consists substantially of two jaws, a, constructed so as to form, when placed together, a cylindrical opening, I),

'ment at its rear end.

at their rear ends and troop-shaped or conical opening, 0, at their front ends. This receiver is mounted upon a projection, d, depend-. ing at right angles to and below the frame B of the machine. The lower end of this projection has fitted to it a journal or hearing surface, e, and a supporting-bracket, f, the bracket extending toward the front of the machine and at right angles to the journal 0, with a pin, g,

projecting upward. When in position the cylindrical opening b of the jaws to incloses the journal or bearing 0, and the under surface of the jaws are supported by the bracket f, the

pin 9 passing upward between thejaws.

Uniting the jaws together and holdingthem in place by its elastic force is a spring, h, which encircles the rear ends of thejaws.

Pivoted to the lower part, it, of the frame B of the machine is an arm or lever, O,which projects in front of the frame and extends through and to the rear of the frame B. The front end of this arm or lever has fixed to it an anvil, D, which anvil is surrounded by a sleeve, Z, and aspiral spring, at, so that the sleeve can be pressed downward around the anvil, and afterward be restored by the resilient action of the spring m. The rear end of the arm or lever (J has one end of a link, 12, pivoted to it, the other end of the link being pivoted to a lever, E, which lever is pivotedat o to the frame B of the machine, and at its upper end isformed with a fork, 19.

The machine is provided with the ordinary operating-lever, F, with a setting-plunger, 1, secured to its front end, and a treadle attach- To this operating-lever, however, and near its rear end, is fixed a tripping device, Gr, consisting of projections s, fixed nearly at right angles to the operatinglever F, and with a roller, t, secured between them.

Now, when my rivetingmachine is constructed substantially in the manner hereinbefore described, and the rivets have passed into the receiver from the channel-way, it is operated by throwing upward, by treadle or otherwise, the rear end of the lever F, which depresses its front end, thereby forcing downward the plunger 0, and at the same time causing the roller t, of the tripping device G to bear against the inner surface of the rear leg 'erly upset on the anvil.

under side of the receiver A, in which position it is rigidly kept, for its rear end, the link a, and the lever E and its pivot, are brought in the same vertical line. (See Fig. 3.) This rigid position of the, anvil enables it to receive the rivet as it is forced through the receiver and to resist the downward thrust of the plunger r, so that the end of the rivet maybe prop- Vhcn the rear end of the operating-lever F is forced downward the roller t of the tripping device G enters into the fork p of the vertical lever E, thereby throwing this vertical lever and the link a somewhat out of the same vertical line. (see Fig. 1,) and by so doing drawing upward the rear end of the arm or lever G, causing its front end and the anvil secured thereto to descend or drop away from the receiver A, permitting thereby the removal or shifting of the goods that are being riveted. As the plunger r descends and forces the rivet through the cup-shaped opening 0 of the receiver A the jaws a spread apart laterally, and as the plunger is withdrawn by its upward stroke from the receiver the spring h restores the jaws to their former closed position. The pin 9, acting as a stop, keeps thejaws from being thrown out of their proper position, and maintains'the receiver in its true place in line with and below the plunger.

The anvill) is surrounded bya sleeve, Z. The upper end of this sleeve projects somewhat above the end of the anvil, affording a better resting-surface for the goods that are being riveted, and when the plunger descends to force the rivet through the goods and upset it on the anvil, the sleeve descends, leaving the end of the anvil D exposed to receive the rivet. \Vhen the riveting is completed the sleeve is restored to its former position by thespring m.

In my rivetingmachine heretofore referred to as patented to me, an upset plate was secured to the lower end of the channel, which reversed the position of the, rivets, compelling them to enter into the receiver point downward; but in my present machine a notch, a, is formed in the jaws a of the receiver, which accomplishes the same purpose-that is to say, as the rivet descends from the end of the chute it strikes within the notch u or against its side, thereby checking the descent of such rivet, and causing it to tumble over into the receiver a.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is- I 1. In a rivet-setting machine, the fixed post 01 and the arms ea, connected by a spring and secured to said post, the rivet-openings in the ends of said arms, and a pin, g, and bracket f, constituting a fixed receiver, combined with the anvil D, its moving-lever, a rivet-feeder, a plunger, and operating mechanism, substantially as shown and described.

2. In a rivet-setting machine, a fixed receiver for the rivets to be inserted, combined with a movable anvil, the lever O therefor, forked lever E, link a, for connecting said levers, and operating-lever I provided with the tripping device G to engage the forked lever, substantially as and for the purpose described.

3. In a rivet-setting machine, the pivoted anvil-bearing arm or lever O, a link, a, and lever E, forked atp, combined with the operating-lever F, provided with the trippingdevice G, to engage the forked end of the lever E, substantially as and for the purpose described.

4. In a rivet-setting machine, an arm, ll, provided with a stationary projection to which is fixed a receiver to take the rivets from the feeder, a plunger, 1*, an anvil, l), and thelever O, supporting such anvil and movablefrom the plunger-operatiug lever through tripping device G, lever E, and link a, substantially as and for the purpose described.

5. In a rivet'setting machine, the jaws of the receiver thereof provided with aspring at their rear ends, and in combination with a bracket,f, and pin g, substantially as shown and described.

6. The arm or lever F, provided with the tripping device Gr, the lever E, provided with the forked end 1), the lever G, carrying the anvil I), and the link a, connecting the said levers G and E, as shown, so that the lever E and link a move into a right line upon the elevation of the anviland hold said anvil positively and fixedly, combined with a stationary rivetreceiver, a plunger, and a feeder, substantially as shown and described.

In a rivet-setting machine, the combination of afeeding-channel, a fixed receiver provided with a notch, u, an anvil, and operating mechanism, substantially as shown and described.
